提示：以下是本篇文章正文内容，下面案例可供参考

一、springboot+模板引擎+mysql+整合mybatis

示例：为了方便

二、使用步骤

1.导入依赖

代码如下（示例）：pom.xml

    4.0.0
    
        org.springframework.boot
        spring-boot-starter-parent
        2.5.6
         
    
    com.oyjl
    spring-boot-name
    0.0.1-SNAPSHOT
    spring-boot-name
    Demo project for Spring Boot
    
        1.8
    
    
        
            org.springframework.boot
            spring-boot-starter-thymeleaf
        

        
            org.springframework.boot
            spring-boot-starter-web
        
        
            com.alibaba
            druid
            1.2.6
        


        
            mysql
            mysql-connector-java
        
        
            org.projectlombok
            lombok
            true
        
        
            org.mybatis.spring.boot
            mybatis-spring-boot-starter
            2.2.0
        
        
            org.springframework.boot
            spring-boot-starter-test
            test
        
        
            org.junit.platform
            junit-platform-commons
        

        
            org.apache.commons
            commons-lang3
            3.6
        
    

    
        
            
                org.springframework.boot
                spring-boot-maven-plugin
                
                    
                        
                            org.projectlombok
                            lombok
                        
                    
                
            
        
    

 编写实体类

package com.oyjl.pojo;


import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.experimental.Accessors;

@Data
@AllArgsConstructor
@NoArgsConstructor
@Accessors(chain = true)  //链式编程
public class Users {
    private Integer id;
    private String name;
    private String password;
    private Integer age;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }
}

 Mapper接口

package com.oyjl.Mapper;


import com.oyjl.pojo.Users;
import org.apache.ibatis.annotations.Mapper;


import java.util.List;

@SuppressWarnings("all")
@Mapper
public interface UsersMapper {
        List finAll();

        Users findUserById(int id);

        int addUser(Users user);

        int update(Users user);

        int delete(int id);


}

 Svrivce接口

package com.oyjl.Service;

import com.oyjl.pojo.Users;

import java.util.List;

public interface UsersService {
    List finAll();

    Users findUserById(int id);

    int addUser(Users user);

    int update(Users user);

    int delete(int id);
}

 Svrivceimpl类

package com.oyjl.Service.impl;

import com.oyjl.Mapper.UsersMapper;

@SuppressWarnings("all")
@Slf4j
@Service
public class UsersServiceimpl implements UsersService {
    @Autowired
    public UsersMapper usersMapper;

    @Override
    public List finAll() {
        List users = usersMapper.finAll();
        return users;
    }

    @Override
    public Users findUserById(int id) {
        return usersMapper.findUserById(id);
    }

    @Override
    public int addUser(Users user) {
        return  usersMapper.addUser(user);
    }

    @Override
    public int update(Users user) {
        return usersMapper.update(user);
    }

    @Override
    public int delete(int id) {
        return usersMapper.delete(id);
    }
}

 mybatis.xml

    
    insert into table_user(name,password,age)
        values (#{name}, #{password}, #{age})
    
    
    update table_user
        set name = #{name},password = #{password},age = #{age}
        where id = #{id}
    

    
    delete from table_user where id=#{id}
    

    
        select * from table_user
    
    
        select * from table_user where id=#{id}
    

application.yml

mybatis:

 controller类

package com.oyjl.conrotller;

import com.oyjl.Service.UsersService;
import com.oyjl.pojo.Users;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;

    }


//添加
    @RequestMapping("/toAdd")

    }

    @RequestMapping("/add")
    public String addPaper(Users user) {

//修改
